Since the reftypes proposal has shipped, we remove the respective flag
and the code that handled its absence. We maintain a WasmFeature for
reftypes for feature detection purposes. We remove the flag declaration
from tests, and adapt some tests that make no sense without the flag.

Element segments and tables in tests used an ad-hoc mechanism to
describe the different types of initializer expressions, e.g. an number
which could denote either the value of a constant or the index of a
global. This CL tidies up and generalizes the test infrastructure by
directly using WasmInitExpr in those cases.
Additional changes:
- Introduce WasmElemSegment class.
- Remove obsolete --experimental-wasm-bulk-memory flag from tests.
- Rename WasmInitExpr.type -> kind.
- Remove dependency of wasm-module-builder from mjsunit.js (except in
assertTraps).

The reference types wasm proposal dropped all subtyping. Subsequently,
the 'anyref' type was renamed to externref.
This changes all references of the *type* anyref to externref.
Additionally, the flag that permits this extension is renamed to
"reftypes" to mirror the proposal name.
